I'm trying to represent a number with leading and trailing zeros so that the total width is 7 including the decimal point. For example, I want to represent "5" as "005.000". It seems that string formatting will let me do one or the other but not both. Here's the output I get in Ipython illustrating my problem:
In [1]: '%.3f'%5 Out[1]: '5.000' In [2]: '%03.f'%5 Out[2]: '005' In [3]: '%03.3f'%5 Out[3]: '5.000'
Line 1 and 2 are doing exactly what I would expect. Line 3 just ignores the fact that I want leading zeros. Any ideas? Thanks!
To pad an integer with leading zeros to a specific length To display the integer as a decimal value, call its ToString(String) method, and pass the string "Dn" as the value of the format parameter, where n represents the minimum length of the string.
For padding a string with leading zeros, we use the zfill() method, which adds 0's at the starting point of the string to extend the size of the string to the preferred size. In short, we use the left padding method, which takes the string size as an argument and displays the string with the padded output.
Use the str. zfill() Function to Display a Number With Leading Zeros in Python. The str. zfill(width) function is utilized to return the numeric string; its zeros are automatically filled at the left side of the given width , which is the sole attribute that the function takes.
The first number is the total number of digits, including decimal point.
>>> '%07.3f' % 5 '005.000'
Important Note: Both decimal points (.) and minus signs (-) are included in the count.
This took me a second to figure out how to do @nosklo's way but with the .format()
and being nested.
Since I could not find an example anywhere else atm I am sharing here.
"{}".format(a)
>>> a = 5 >>> print "{}".format('%07.3F' % a) 005.000 >>> print("{}".format('%07.3F' % a)) 005.000
More python3
way, created from docs, but Both work as intended.
Pay attention to the %
vs the :
and the placement of the format is different in python3.
>>> a = 5 >>> print("{:07.3F}".format(a)) 005.000
>>> a = 5 >>> print("Your Number is formatted: {:07.3F}".format(a)) Your Number is formatted: 005.000
"{}".format(a)
NestedThen expanding that to fit my code, that was nested .format()
's:
print("{}: TimeElapsed: {} Seconds, Clicks: {} x {} " "= {} clicks.".format(_now(), "{:07.3F}".format((end - start).total_seconds()), clicks, _ + 1, ((_ + 1) * clicks), ) )
Which formats everything the way I wanted.
20180912_234006: TimeElapsed: 002.475 Seconds, Clicks: 25 + 50 = 75 clicks.
@babbitt: The first number is the total field width.
@meawoppl: This also counts the minus sign!...
